A week after macOS Sierra's move to beta 4 launching the set, Apple has made the latest watchOS 3.2.3 beta available for developer testing alongside a pair of very minor developer's updates for iOS 11 and tvOS 11.
The watchOS update installation is more complex than the other updates, requiring that people use the official Watch app for the iPhone, and have their Apple Watch plugged in nearby with at least 50 percent charge.
There appears to be no new feature additions in the latest watchOS beta, that sports build number 16G71a.
Apple has not made any significant changes to the release notes that accompany the update. There are some known issues with Xcode, but those remain from previous iterations.
Also running are the second betas for developers on iOS 11, macOS 10.13 High Sierra, watchOS 4 and tvOS 11. Also on Monday, Apple issued slightly revise betas of iOS 11 and tvOS 11. The new iOS 11 release is now build number 15A304j versus 15A304i, with tvOS getting boosted to 15J5310h from 15J5310e.
Apple's iOS 11 appears to carry the most changes, with upgrades to Siri, Apple Pay, Photos and a general user interface revamp.
The macOS High Sierra update contains a number of refinements and other improvements like Apple File System integration, migration from H.264 to H.265, and Metal 2.
